Path

Path

The Path class manipulates file path strings without touching the filesystem — combining segments, extracting file names, and getting extensions. Path.Combine builds a correct path for the current operating system, avoiding manual slash handling. Using Path methods instead of string concatenation avoids cross-platform path bugs.

Note: Always use Path.Combine instead of manually concatenating folder names with / or \\.

Example: Path

using System;
using System.IO;

class Program
{
    static void Main(string[] args)
    {
        string fullPath = Path.Combine("data", "reports", "summary.txt");

        Console.WriteLine(fullPath);
        Console.WriteLine(Path.GetFileName(fullPath));
        Console.WriteLine(Path.GetExtension(fullPath));
        Console.WriteLine(Path.GetFileNameWithoutExtension(fullPath));
    }
}
